工作中用到的Cookie技巧

創建Cookie
HttpCookie myCookie = new HttpCookie("test");
   myCookie["t1"] = "t1" ;
   myCookie["t2"] = "t2" ;
   myCookie["t3"] = "t3" ;
   myCookie["t4"] = "t4" ;
   myCookie.Expires = DateTime.Now.AddSeconds(25);
   
   Response.Cookies.Add(myCookie);
讀Cookie
this.Label1.Text = Request.Cookies["test"]["t1"];
    this.Label1.Text += "<br>"+Request.Cookies["test"]["t2"];
    this.Label1.Text += "<br>"+Request.Cookies["test"]["t3"];
    this.Label1.Text += "<br>"+Request.Cookies["test"]["t4"];
延長生命周期
HttpCookie test = Request.Cookies["test"];
   test.Expires = DateTime.Now.AddSeconds(25);
   Response.Cookies.Add(test);
增加一個子健
HttpCookie test = Request.Cookies["test"];
   test["tt"] = "tt";
   test.Expires = DateTime.Now.AddMinutes(5);
   Response.Cookies.Add(test);
讓Cookie過期
Response.Cookies["test"].Expires = DateTime.Now.AddMinutes(-1);
